IIR FILTER _ DESIGN . USING MODEL REDUCTION TECHNIQUE

Abstract

Work deals wjth the design of IIR filter from the FIR filter using impulse response gramian technique The algorithm is based on the concept of balanced model reduction. It involves, designing a FIR filter satisfying the given specifications and subsequently obtaining a significantly lower order IIR filter using model reduction based on impulse response gramians. Various examples of designing IIR filter from. the FIR filter are also. included.
